The OECD has published a Guideline that presents a method for unambiguous characterization of hydrocarbon solvent mixtures. Actual risks can be evaluated reliably only when the identity of the substance is known. Once that occurs, regulations and laws can be applied appropriately.

Some of the solvents can be described well, but others are characterized as substances of Unknown or Variable composition, Complex reaction products, or Biological materials (UVCB). The guideline is helpful for characterization of
these solvents.

If you deal with substances of unknown composition and want to make sure
that you’re covered legally, please contact us at reach@kft.de.
